Specifieation of Letters Eatent.

Patented July 28, 1908.

To all whom it may concern:

Be it known that we, Airoits'r NEUsUs and BENJAMIN F. GIBLER, citizens of the United States, residing at Winslow, in the county of Stephenson and State of Illinois, have inin 'lank-Hea-ters, of which the f0 lowing is a Our invention relates to tank heaters and simple inexpensive and highly efficient device to be placed in watering troughs or tanks and to prevent the same from freezing in cold wea ier.

()ur'invention further and specifically retion, arrangement and o eration as willbe hereinafter described wit reference to the accompanying drawings forming a part of this specification, in which like numerals are used to designate like parts throughout the several figures, and in which Figure 1 is a top plan view of our improved apparatus, Fig. 2 'is a horizontal sectional view taken on the line 2-2 of Fig 3, and-Fig. 3 is a vertical sectional view taken on the line 3-3 of Fig. 2, and illustrating the same with- In the practical embodiment of our invention we provide a preferably water tight rectangular casing 1 having an air shaft 2 end, transverse water pipes 3 and 4 connecting the sides .of the casing 1 adjacent each end thereof, the pipe 4 being arranged slightly above the pipe 3, and both of said pipes having flanges 5 bolted to the sides of the casing l. The ipe 3 isadapted for use t 1e pipe 4 as the water outlet, as is shown by the arrows in Fig. 2

verse pipes 3 and 4 are connected by means ipes 6. A suitable heater 7, which I have s own in the drawings as an oil burner fed through a pipe ries of pipes 6 and is adapted to heat the same to a degree sufficient to take the ext-reme chill from the water in its passage therethrough. For a quicker and more uniform heating of the pipe 6, I preferably arrange just above the same a shield 10 connected to the sides and ends of the casing 1 by means of straps 11. Air is supplied-to theheater 7 through the air shaft 2, the amount of air assing therethrough being regulated by a s ide 12 arranged in the upper end thereof. The so py of air and the draft is further controlled by the draft regulator 13 arranged in the top of the casing 1.

The entire apparatus as described is adapted to be placed within a water tank or trough A to allow the water in said tank or trough to circulate through the same whereby it may be heated sufficiently to prevent it freezing. Having thus fully described our invention, we claim:

guides at Ina device-of the characterdescribed, the

flanges adapted to be secured to said casing, I

aplurality of longitudinal inclined water circulating pipes connecting said transverse pipes, a heater arranged below said: pipes, a

cat shield arranged above said pipes and provided with straps for attachment upon the inner surface of sa d casing, an an" shaft formed at one end of said casing, said shaft opening through the top thereof and extending downwardly to said shield, aslide .mounted adjacent the mouthof said, airshaft .to regulatethe volume of air,"and a draft regulator formed in the top of said casing at the op osite 'end thereof 'r shaft, to regu ate the draft through said casing, substantially as described. In testimony whereof we affix our signatures in presence of two witnesses.
